Port to glib/gtk+ 2.0 episode I (every segfault has it's beginning)
2001-07-24 Michael Natterer <mitch@gimp.org>
Port to glib/gtk+ 2.0 episode I (every segfault has it's beginning)
* configure.in: require glib/gtk+ >= 1.3.7, commented out the
gtkxmhtml stuff.
From now on, you will need glib, pango, atk and gtk+ HEAD from CVS
to hack or use GIMP HEAD.
Beware, it crashes randomly :)
* app/core/Makefile.am
* app/core/gimpmarshal.list: new file plus rules to generate
gimpmarshal.[ch] from it.
* app/core/*
* app/tools/*
* app/widgets/*
* libgimpwidgets/*: started to use the glib object system. All
core/ objects are still gtk objects however. All signals are
created using g_signal_new(). There are many gtk+ artefacts left.
Finally, we will _not_ use the gtk_signal_foo() wrappers and
friends any more.

To optimize duplicate and/or wrong image updates away, introduced new
2003-09-06 Michael Natterer <mitch@gimp.org>
To optimize duplicate and/or wrong image updates away, introduced
new policy that a child object must never explicitly update or
invalidate its parent object (just like the GUI is not updated
explicitly by the core):
* app/core/gimpdrawable.[ch]: added new signal
GimpDrawable::update(). Never update or invalidate the image when
the drawable is updated or invalidated.
(gimp_drawable_set_visible): don't gimp_drawable_update() the
drawable since its pixels have not changed.
* app/core/gimpimage.[ch]: connect to the "add" and "remove"
signals of the layers and channels containers. Also connect to the
"update" and "visibility_changed" signals of all drawables in
these containers (optimizes away updates issued by drawables which
are not yet added to the image and updates of the selection
mask). Also, don't propagate updates to the image if the emitting
drawable is invisible (optimizes away updates issued by invisible
drawables).
(gimp_image_add_layer,channel)
(gimp_image_remove_layer,channel): don't update the image since
that's done by our "add" and "remove" handlers now.
(gimp_image_position_layer,channel): update just the image, not
the drawable since its pixels have not changed.
(gimp_image_real_colormap_changed)
(gimp_image_set_component_visible): always call
gimp_image_update() *and* gimp_viewable_invalidate_preview() to
get everything updated, since update and invalidate of images are
not connected.
* app/core/gimpimage-undo-push.c (undo_pop_layer,channel): don't
update the drawable since (a) its pixels don't change and (b) the
image updates itself upon adding/removing now.
(undo_pop_layer_mod): replaced gimp_image_update() by
gimp_drawable_update() (just for consistency with other similar
functions).
* app/core/gimplayer.c: connect to "update" of the layer mask and
issue updates on the layer if the mask update has any effect on
the projection.
(gimp_layer_create_mask): don't set the mask's offsets here since
they may be different when we later add the mask to the layer.
* app/core/gimplayermask.c (gimp_layer_mask_set_layer): set the
mask offsets here instead.
* app/core/gimpchannel.c (gimp_channel_translate): update the
channel even if push_undo == FALSE.
* app/paint/gimppaintcore.c (gimp_paint_core_finish)
* app/tools/gimpinktool.c (ink_finish): invalidate both the
drawable and the image preview since invalidating the drawable
doesn't invalidate the image any more.
* app/text/gimptextlayer.c (gimp_text_layer_render_now): also
update the new extents of the text layer, not only the old one.
(gimp_text_layer_render_layout): don't update the drawable since
gimp_drawable_fill() already updated it.
